Editing Emergency population warning (section)

==Requirements==

In order to develop an effective emergency warning system, certain things are required:

* an agreement as to what constitutes an emergency in the area served by the system. This differs from region to region depending on the local climate, geology, and the like.
* an agreement as to who can initiate an alert. In some countries all warnings are transmitted by a single [[command center]], while in other larger countries a host of local, regional, and national agencies can be authorized to initiate warnings.
* a system or systems by which the information can be quickly transmitted to the population. Including the method and technology used. 
* an education program to teach the general public how to recognize an alert or what to do if a warning is broadcast.
